Pocket Tachometer (Contact)

Model MT-100

FEATURES AND BENEFITS

The MT-100 tacho met er i ncorpora tes the lat est
microprocessor technology and offers:

• Multiple measurement types: total revolutions (rev); revolu­tions per minute (rpm); surface speed: m/min, y/min, in/min,
ft/min; and length: meters, yards, feet and inches.

• Compact, pocket-size design

• 14 reading memory: minimum, maximum, final, 10 select­able measurements and an average of memory measure­ments, up to ten.

• Efficient design; long battery life and continuous opera­tion.

• Automatic converion of units.

IMPORTANT SAFETY INSTRUCTIONS

When using the master wheel, do not use an
extension shaft as the wheel may come off of the
shaft and cause damage or injury.

Congratulations on the purchase of our MT-100 contact
tachometer. We trust you will enjoy many years of
professional results from your product.

Please read the entire instruction manual thoroughly before
initial set-up and operation; the information contained
herein will aid you in operating your tachometer safely
and with excellent results.

INSPECTION/STANDARD ACCESSORIES

If upon delivery shipping damage is detected, do not
operate the tachometer. Notify shipping carrier immediately
for damage claim instructions. Refer to nameplate
and record the serial number for future reference.

Items included with the MT-100:

• Carrying case

• 3 manganese AA batteries

• Cone adapter

• Funnel adapter

• 6" circumference wheel

• NIST certificate

• Instruction manual

Although the tachometer is able to achieve higher
measurements than what is listed, the master wheel
has a maximum speed limitation of 5000 ft/min (for
safety reasons).

OPERATION

Contact measurements

Measuring rotation speed using the cone or funnel-shaped
contact probe:

1. Attach the cone or funnel adapter to the tachometer
by placing on the adapter shaft. Align the shaft pin
with the notch of the adapter stem.

2. Press the POWER button to turn the tachometer on.

3. Select RPM (revolutions per minute) or REV (total
number of revolutions) by pressing the UNIT button.

4. Press and hold down the POWER button to start mea­suring.

5. Bring the contact probe into contact with the object
to be measured by touching the contact probe slowly
to the center of the rotating object. If the measuring
range of the tachometer is exceeded, “OVR” will ap­pear on the tachometer’s display.

6. Press and hold the POWER button to take another
measurement.

7. Press the UNIT button to convert between ranges.

When a high-speed rotating object is measured
for hours using a cone or funnel-shaped contact
probe the surface of the probe in contact with
the object may become very hot.

Measuring surface speed and distance using the 6"
circumference wheel.

1. Attach the 6" circumference wheel to the tachometer
by placing the wheel on the adapter shaft. Align the
shaft pin with the notch of the wheel stem.

2. Press the POWER button to turn the tachometer on.

3. Press the UNIT button to select measuring unit: meters/
minute [m/M], yards/minute [Y/M], inches/minute [I/
M], feet/minute [F/M], meters [m], yards [YRd], inch
[IN], or feet [FT].

4. Bring the 6" circumference wheel into contact with the
object to be measured by slowly touching the contact
wheel to the moving object.

5. Press and hold down the POWER button to start mea­suring.

6. Press the UNIT button to convert between ranges.

Memory Function

The tachometer’s memory capabilities are as follows:

1. Minimum, maximum and last measurements are re­corded automatically by the tachometer.

2. Ten selectable measurements can be programmed into
memory by pressing the MEM button while the POWER
button is fully depressed (M1, M2, M3, … M10).

3. The average value of sequentially stored memory, up to
ten, can be viewed by pressing the memory button.

Note: if the memory button (MEM) is not selected while the
POWER button is pressed the measurement will not be re­corded into its memory location, The memory will be recorded
automatically into memory if the measurement made is the
maximum, minimum or last measurement.

To delete stored memories do one of the following:

1. Press the MEM button for five seconds or more. All
memory will be erased after [CCCCC] is displayed.

2. Changing the units of measurements and then making
additional measurements.

3. Memory will be automatically erased if the TACHOM­ETER turns off automatically after five minutes.

Battery Replacement

When “LO BAT” flashes on the display, replace the batteries
with new ones.

To replace the batteries:

1. Slide open the battery cover (located on the rear of
the tachometer).

2. Remove old batteries and insert three fresh AA size
batteries, observing proper polarity. Do not mix old
and new batteries.

3. Slide the battery cover back into place.

Note: Do not mix old and new bartteries, and when replacing
batteries, use AA batteries. The tachometer may be damaged if
liquid leaks from the batteries. This may happen if the batteries
are left inside the tachometer's enclosure for long periods of
time. Remove the batteries after using the tachometer.

When making surface speed or distance mea­surements, ensure that the 6" circumference
wheel’s perimeter is parallel to the object to be
measured.

Note: When using the master wheel, accuracy can be affected
as much as 0.3% of reading.
